SID stands for how often to dose?

• A. twice a day
• B. once a day
• C. every other day
• D. as needed

Answer: (B)

SID stands for semel in die, meaning once per day. This shorthand in veterinary prescribing shows you should give the drug one time within each 24-hour period, with the exact time flexible as long as it’s about every 24 hours. Other schedules have different meanings: twice daily means two doses in the same day, every other day means roughly once every 48 hours, and as needed means the dose is given only when the animal shows symptoms or as directed. Remembering SID as once daily helps ensure dosing is consistent and appropriate for maintaining drug levels.
